FCB B-mill

Printable Version


The ball mill is traditionally the basic system used for the grinding of raw material, clinker and additives in a cement plant, as well as a wide range of minerals.
Benefiting from a large experience, the FCB B-Mill has been designed to be particularly well adapted for the grinding of products at high fineness and grinding of very abrasive products and solid fuels.

Customized design

Because each grinding process has its own characteristics and constraints, Fives designs fit-to-process solutions.

  • From very large to small mill size
  • Air swept mill or a bi-rotator mill
  • Fitted with a single chamber or two chambers
  • Fitted with a pre-drying chamber or drying compartment with lifters in case of moist additives.

Flexible and reliable drive system

Drive system will be selected according to the mill power, from girth gear with single pinion drive (up to 3,900 kW) or double pinion gearbox (up to 8,000 kW) to central drive (up to 12,000 kW), and will include barring drive with clutch system for maintenance operations.

Technical features

Pioneering shoe-bearing technology

For large mills, Fives has developed a pioneering technology consisting in supporting the tube mill by tyres integrated into the mill shell, sliding on shoe bearings. This technology enhances the level of safety and guarantees a minimized maintenance cost.

The FCB shoe bearings technology offers:

  • Effective load pressure ensured by only one shoe bearing at each end of the mill
  • Shoe bearings mounted on Teflon-stainless steel swivels to allow oscillation to the sliding tyre 
  • Natural formation of hydro-dynamic oil film by off-centre swivel
  • Equal under-load local deformation of sliding tyre and shoe bearing, ensuring the permanence of the hydro-dynamic oil film
  • Lubrication system adapted to every operating phase (normal operation, barring maintenance, cooling period) with necessary monitoring and safety interlocking
  • Detection of abnormal stresses by separate hydro-dynamic axial thrust with safety interlocking
  • Special design for easy access for inspection and maintenance allowing shortest shutdown period.

Customer benefits
